KB890830 KB929338 KB905474 Monitor Distortion

After installing these 3 updates my monitor is now distorted. It only
displays 2/3rds across with a black part of screen to the right. In addition
a new row exists below the Start button, etc. Also, a portion of the screen
repeats itself to the right (approximately 1/4 inch). Go figure!!

Anyone else have a similar experience and know of a fix? I have a Toshiba
laptop and it runs like a charm except for this latest monitor craziness
which just happened after the 3 updates.
